Demi Lovato is heartbroken. While the singer's long-term relationship with actor Wilmer Valderrama is still intact, she's hurting over the recent loss of her dog Buddy.

On Tuesday, Lovato shared the sad news that the adorable dog she brought home last December had died in a "tragic accident."TMZ later reported that Lovato discovered Buddy's mauled remains in her backyard after a coyote slipped in and attacked him.

Bill Cosby's lawyer Monique Pressley had a busy Friday, making the media rounds to once again deny that her client had ever raped or sexually assaulted even one of the 46 women who have publicly accused him of doing so.

On CNN, Pressley compared the women to a lynch mob, saying Cosby is being unfairly raked through the mud.

"Through the decades, we have seen what we used to call lynch mobs, where people turned and pointed the finger at one person and accused that one person of doing something that they did not do, and they were filed into the court, one after another, to say, 'He did it, he did it, she did it, she did it' when it was not the case,” Pressley told CNN's Ashleigh Banfield. "That happened often in the ’60s and ’70s in this country."

It's been eight months since the Guardians of the Galaxy star, 37, welcomed her sons, Cy and Bowie, and while it's been hard work raising twins (listen to her talk about sleep-training… gulp), that's not the only challenge she's faced. Shedding the extra baby weight — Saldana weighed up to 185 pounds while pregnant, she revealed — is something she's worked hard on. Now, she's showing off her impressive results.

Almost there! It's been difficult but so rewarding. I feel strong. All it takes is determination! Mommies we can all do it, damn it!!!

TMZ reported Friday morning that the Oscar winner shared dinner on her 41st birthday with Kasey Stewart, one of the losing contestants on Desiree Hartsock's season of The Bachelorette in 2013. The website claimed the that the two were "getting cozy" at Gjelina, a trendy restaurant with a New American menu of oysters, veggies, and pizza near L.A.'s Venice Beach.

Stewart, who's now 32, even shared a photo Thursday of the pair smiling next to a fireplace along with the caption: "Happy Birthday to this beautiful soul. @hilaryswank."

Change is hard — just ask the Kardashian clan. According to Khloé, she and her sisters haven't completely adjusted to the arrival of Caitlyn Jenner.

"We, my sisters and I, we will call Caitlyn 'Bruce' and we've been told that's completely fine," the 31-year-old reality star revealed Thursday during an interview on Australia's The Project. She added that they "don't like to say that Bruce is gone, per se."

It it seems that it's especially hard to leave Bruce behind while talking on the phone.

"And she told us, we are allowed to call her any name we want to. Because on the phone, when she calls me, it's the same voice as Bruce," Khloé reasoned. "And if I'm not physically with her, it's hard to remember in the moment that I'm talking to Caitlyn, if that makes sense."

But just because it may be tough doesn't mean Khloé isn't completely behind her stepfather's decision to take his journey public.

Cosby Show reruns. Jell-O Pudding Pops commercials. Comedy-album routines about "Spanish fly." There is almost no bit of Bill Cosby-related entertainment that hasn't triggered a re-assessment in the wake of his his serial-rape scandal. Something else to add to the list: Cosby biographies for children.

There have been a handful of these books written over the years with perfectly fine titles that now play as irony or worse: Bill Cosby: Coming at You , Bill Cosby: Family Man , Cool Cos: The Story of Bill Cosby .

Cool Cos , published in 1969 by Scholastic, is one of the earliest — if not the earliest — Cosby biography for any aged audience.

"Believe it not, that book sold a million copies," says its author, Joel H. Cohen, a veteran writer of biographies for children. "He was just beginning to make it big at this point... There was no hint of scandal."

A sampling:

"Oh, wow. I didn't recall that," Cohen says of the passage in the biography.

The truth is, we would watch Helen Mirren do just about anything. However, seeing the dame meet her wax figures ranks among her greatest performances.

The Academy Award winner, 70, had a grand time getting up close and personal with her look-alikes at Madame Tussauds in London on Thursday. The acting legend, who loves wearing "stripper shoes," dyes her hair crazy colors for fun, and rocks a bikini better than women half her age, goofed around with the replicas and checked to make sure they were up to her standards.

It is unclear if she was impressed, but apparently her husband, director Taylor Hackford, was. She quipped, "My husband wants to marry her. I'm much more argumentative than she is."

We think they're all pretty fierce — just like the woman they pay tribute to.

The 30-year-old singer/actress/sibling of Jessica and her husband, actor/singer Evan Ross, have welcomed their first child together, a daughter. According tomultiple reports, baby made her big debut on Thursday night and joins Ashlee's 6-year-old son, Bronx, from her previous marriage to Pete Wentz. The couple has not yet revealed the baby's name.

The pair talked baby names on The Wendy Williams Show in February, with Ross, 26, saying that while the name wouldn't be "any Apple, Orange, anything like that," he promised it was "going to be different."

Ashlee, who did Tracy Anderson's prenatal workouts throughout her pregnancy, was on the red carpet as recently as June 25 when she and Ross attended an event at the W Los Angeles. Dressed in black, she cradled her baby belly as she posed for photographs with her husband.

Then: Actors Kurt Russell and Goldie Hawn found romance when they co-starred in the 1984 movie Swing Shift , not long before this photo was taken. Goldie's daughter Kate Hudson — who was raised by Russell and has often been estranged from her birth father, Bill Hudson — shared the pic today, captioning it, "#tbt 80's Ma and Pa." The coordinated outfits, the retro Pepsi can, and Goldie's super-colorful bag are serious throwbacks!

Now: More than 30 years later, Kurt, 64, and Goldie, 69, are still together. They've both continued to be close with Kate, 36, as she's proven with images that she's shared over the last few months, including one with her look-alike mother in May and another of Kurt on his birthday in March. Back then, Kate called Kurt, "the most dependable, strong, authentic, loving and fun Dad!"

Proving that even supermodels have less than glamorous days, the blond beauty was photographed looking refreshingly normal while leaving Joe Jonas's house after a sleepover earlier this week.

The 5-foot-10 stunner actually appeared younger than her 20 years as she strode out of his L.A. home with a bare face, some bed head, and a serious lack of eyebrow pencil (which she seems to really fancy). The Balmain babe also had on a blue Statue of Liberty T-shirt that she probably grabbed from her beau's clothes giveaway pile.

The shirt definitely wasn't as awesome as the one Hadid wore the other day. While out to lunch with the 25-year-old singer, whom she has been dating since May, she wore a tee that said "G.I." while standing next to him, a nod to the celebrity couple name, G.I. Joe, Cara Delevingne gave them.

With that type of a laid-back attitude, we doubt she cares that anyone is talking about her bed head.
